func Parse(registryURL string) (*url.URL, error)
Parse parses and validates a given serverURL to an url.URL, and returns an error if validation failed. Querystring parameters are omitted in the resulting URL, because they are not used in the helper.
If serverURL does not have a valid scheme, `//` is used as scheme before parsing. This prevents the hostname being used as path, and the credentials being stored without host.
